Now referring to the figures of drawings, one specific form of the invention will be described. The machine is of a type adapted to knit seamless hosiery and has a cylinder I rotatable in the usual way upon a. circular base 2. This cylinder has the usual latch needles and sinkers functioning with those needles, said needles being carried in a sinker head 3 above which is a sinker cam cap 4. A carrier ring 5 is pivoted at 6 on a post 1. As in Fig. 3, this carrier ring has a plurality of yarn feeding levers 8 pivoted in an extension 9 to the carrier ring and these yarn feeding levers are controlled to feed and change yarns as in United States Patent #933,443.

Upon a cam plate I and at the right hand side of the machine, are mounted the usual needle cams such as effect stitch drawing in this type of machine. Those cams are not shown in detail, but will be described more specifically with reference to Fig. 29.

Wrap yarns are to be fed to certain selected needles by mechanism such as illustrated and described in United States Patent #1,702,608 and in this case the only part of that mechanism shown is a wrap yarn feeding spindle II, disc I2 and eyelets I3 through which the several Wrap yarns are threaded and fed. At the side of the circular base 2 a spindle I4 is rotatable and is driven by gears I and I6, Fig. 5, and through other gearing (not shown) serves to rotate the spindle II at a 1 x 1 ratio with the. needle cylinder. Spindle I4 is guided in a bearing in bracket I1, said bracket extending upwardly as a post I8 to support other elements of the wrap mechanism all as shown inthe patent just above men- I tioned.

'I'he circular base 2 is attached at the upper side of the usual frame I9, Fig. 5, and that frame has rotatable in suitable bearings a main cam shaft upon which are drums 2I and 22, Fig. 9.

This cam shaft makes one revolution for each knitted stocking produced and the usual cams along with other cams later to be described, control the various functions of the machine. The only cams necessarily described here are those which affect feeding of the auxiliary yarn also control the pattern means at the back of the machine for the raised part of the fabric.

At the front of the circular base V2 is attached a bracket 23 and that bracket carries a pattern drum 24 rotatable on a spindle 25. The spindle 25 is really supported within an arm 26 pivoted on the bracket at 21 and guided at its otherl end by a shoulder screw 28 extended through a slot 29. A spring 30 is attached to the bracket and to the arm 26 and serves to pull that arm inwardly against an adjustablefstop screw 3II. A lever 32 pivots at 33 and by means of a connecting lever 34 and link 35, the drum 24 may be moved away from the cylinder when no wrap pattern is to be formed.

The drum 24 has a plurality of discs :xed thereto, each of said discs having frangible butts 36, it being understood that these butts may be broken oi according to any desired pattern. A11

of the butts are shown intact here since this matter of setting up a pattern is one which a. skilled knitter or knitting mechanic can do. The drum is ratcheted periodically by mechanism shown in` United States Patent #1,702,608, that mechanism including pawls 31, a plate 38 and a link 3B. The link 39 connects to other mechanism all of which is shown here since it is adequately described in the patent to which reference is made.

A series of plungers 40 (shown more clearly in Fig. l14) and guided within a bracket generally indicated by numeral 4I, are contacted by the butts 36 and are moved inwardly or outwardly to and from the needle cylinder in accordance with the set up of the pattern. These plungers engage selecting butts such as the but-t 42 or 43, Fig. 14, on jacks 44 and serve to select those jacks by imparting a short vertical movement thereto. Each jack has a master butt 45 the purpose of which will be described more fully as the disclosure progresses. The cam-ended plunger 46 works upon a butt at the upper end of one-half of the jacks (those at the sole side of the machine) and make it possible to pattern in the instep while making the sole of the stocking plain. This cam is drawn inwardly by a spring 41 and is moved out by a lever 48 pivoted at 49 and which hooks against a projection 50 at about the central part of the plunger. Link 48 connects to the lever 48 and controls knitting an unpatterned sole from suitable cams (not shown).

At the back of the machine and on the left hand side, mechanism is provided by means of which the needle jacks are selected to produce a. 1 x 1 simulated rib top and also for the purpose of producing the raised fabric pattern throughout the leg and foot or other desired areas of a fabric. That jack selection is brought about by a pattern drum generally indicated by numeral 5I, Figs. 1, 3, 13, 15, 16, 17, 23 and 24. That drum carries a plurality of pattern discs having frangible butts 52 which contact a series of levers 53, there being one lever individual to each row of butts 52. Those levers 53 are guided by the spacers 54 and pivoted within a supporting bracket 55. Springs 56 maintain the toe ends of these levers in contact with butts 52 or with the discs in the event butts are broken away.

The levers 53 engage at their opposite ends with a second group of levers 51, these levers having their inner ends so constructed as to engage the butts 42 to raise jacks 44 as they are selected preparatory to causing their needles to take the auxiliary yarn. Upon being selected,

the jacks move vertically until their master butts 45 contact a master cam 58 whereupon the needles are raised to clearing and yarn taking height. After being raised up cam 58, the butts 45 engage and are drawn down by a cam 59, these cams being better shown in a diagrammatic view, Figs. 19 and 29.

The drum 5I and mechanism appurtenant thereto are mounted on a swinging bar 60, Figs. 23 and 24, that bar pivoting at 6I and being urged by a spring 62 in a direction to engage the toe ends of the levers 53. A stop screw 64 is adjustable and limits movement of the bar as the drum moves to active position. To move that drum outwardly, a bell crank lever 65 connected to a link 66 is actuated as shown in Figs. 23, 24 and 25 and by means of connecting linkage and cams on the drum 2| all as will be described in detail in a later paragraph. The drum 5I rotates on a spindle 61 and is ratcheted by means of pawls 68 and 89, Figs. 15 and 17, those pawls being pivoted at on a plate 1| having arms 12 and 18. Springs 14,` one for each pawl, maintain them in contact with teeth 15 on the ratchet wheel 16.

A link 11 connects to the arm 12 and then extends across connecting to a bell crank lever 18, Fig. 4, one arm of which engages behind the lever 19. This lever 19 is contacted by certain cams on the 104-tooth gear and is thereby periodically moved to and iro to impart ratcheting movement to the front drum later to be described, that same motion being availed of to ratchet this drum 5|.` The lever 19 and its motion from the 104-tooth gear are fully described in United States Patent #2,211,785.`

This drum 5| is retimed at appropriate intervals by mechanism shown in Figs. 3, 15 and 17. The ratchet wheel has one short tooth 80 and the pawls 68 and 69 which are normally urged inwardly against the ratchet wheel teeth may be drawn outwardly by means of a detent 8| connected to a bent bracket 82. The detent 8| contacts pins 83 and 84, the pin 88 projecting from the top pawl 69 and the pin 84 from the lower pawl 68.

During the knitting of the heel, drum 5| is stopped entirely and does not start again until the heel is finished and the foot commences. At that time both pawls are completely out of contact with ratchet wheel teeth as shown in Fig. 15, and also, the ratcheting means is stopped by means shown in Figs'. 31 and 32.

In these figures the lever 19 is shown in practically its outermost position and when the ratcheting of drum 5| and also drum stopped, a bell crank lever 19' pivoted at 80' .comes into the position of these Figs. 31 and 32,

holding lever 19 outwardly so fected by the cam or cams which actuate it. A link 8|' connects to bell crank lever 19 and to a second bell crank lever 82' which derives movement through a depending link or rod 83'. The link 83 extends down to other mechanism controlled by cams on one of the main cam drums and which initiates the stopping of the above mentioned ratcheting motion at the proper times.

During knitting the toe of a stocking, the drum is moved away from the pawls only far enough that it is not afso that they fail to engage the short tooth 80.

That means that the drum will be retimed as it is ratcheted up to the tooth 80 and will not start again until the pawls are allowed to engage to the fullest depth of the teeth.

The bracket 82 is fixed to extension 85 which projects from the rear part of the circular base.

Those parts are stationary. The pawls are withdrawn when the bar is moved to move the drum away from itsv active position. Of course the ratchet movement of plate 1| takes place no matter what the position of the drum.

As shown in Figs. 1, 3, 15 and 16, the topmost one of the levers 53 is specially controlled by a bell crank lever 86 pivoted at 81 and connected by a link 88 to the end of that topmost lever. This bell crank lever 86 is connected at its other end to a depending link 89 which extends downwardly to mechanism hereinafter to be described and by means of which properly timed impulses are imparted to the top lever 53.

Now referring to Figs. 1, 3, 18 and 19, an auxiliary stitch cam 90 is ilxed to the end of a lever 9| pivoted at 92 on an extension 93 to the cam plate I0. 'I'his leverextends outwardly from the pivot 92, and by means of a spring and to the end of lever to elongate as its lower maintains the toe |05 94, the lever is swung in -such a direction that stitch cam will normally be held inwardly against the needle cylinder.

A lever pivoted at 96- extends upwardly as at'91 and then horizontally at 98 having connected thereto an angular piece 99 the end |08 of which is hooked about lever 9|. A link |0| connects to the outer end of lever 95, and whenever that link ls drawn downwardly, the hook end |00 will engage and draw lever 9| 'and stitch cam 90 out away from the cylinder to a position in which the cam will not contact any of the butts.l Link |0| extends downwardly and connects to a lever or arm aifectedby certain cams on drum 2|.

Now referring to Figs. l, 3, 5, 9, 10 and 11, the drum 2|, cams thereon and connections to cern links above mentioned are shown. In Figs. 5 and 9 the outermost lever |02 pivotedA at |03 on the bracket |04 has a toe |05 which engages upon a row of cams including the cams |06 and |01. The lever |02 is connected to the lower end of link 89. A spring |08 connects to the lever |02 and to a ilxed part of the machine and in contact with one of the cams or downwardly on the cam drum.

Whenever the toe of the lever rides on one of the cams |06 or |01, the link 89 is pulled downwardly and the topmost lever 53 outwardly thereby projecting the appropriate plunger inwardly against the cylinder to engage and select jacks. The spring |09 is connected to link 89 02 and allows the link end slides in the clevis The second lever II has a toe |2 which bears upon cams ||3 and IH on the drum 2|. lever is oiset to the side and connects to the lower end of the link 66, that is, the link which connects to lever 65 to move the drum 5| for making a plain sole and also for stopping the pattern controlled by that drum altogether.

The third lever |5 has a toe 6 and an offset or bent projection ||1 to which is attached the lower end of link or rod |0| by means of which the auxiliary stitch cam 90 is pulled away from the cylinder. The toe ||6 is controlled by cams ||8 and ||9 which are properly positioned on drum 2| to effect the Withdrawal of the cam 90 when desired.

Now referring to Fig. 26, the cams just described and which are xed to the drum 2| are shown in the relative positions which they occupy. Cam |06 lifts the toe of lever |02 and pushes the stop selecting plunger inwardly to make a 1 x 1 type rib construction at the beginning of the stocking top; that cam controls throughout the leg until the heel is reached. After dropping off cam |06 the plunger is out until starting the foot again at which time the cam |01 raises the toe |05 of the lever |02. At the start of the toe the plunger is again withdrawn and the toe of the lever rides on the drum throughout the toe, loopers rounds and throughout the starting of the top to a point where the 1 x lfconstruction again commences.

Cams 3 and I4 which govern the so-called raised pattern are effective in the toe and throughout the start of the top, and in the heel, respectively. After going out of the foot, the drum 5| is moved away from levers 53 so that no raised pattern effect is possible until again starting in the leg. Of course, the top plunger controlled by the rst part of cam |06 causes 1 x l raised fabric to be knitted Just prior to starting in the leg.l Cam ||4 along withI cam |06 prevents any type of raised pattern effect in the heel. According to the present set up 1 x 1 type simumted rib 1s knitted throughy tain mechanism in the sinker cam cap 4. This drum has a series of discs, each of which has a plurality of butts |2| 4which are removable and whereby a pattern is set up on the drum for controlling the position of a series of .plungers |22. These plungers |22 contact butts on jacks |23. and those jacks, in turn, control the position of sinkers |24, all as described in Unitedk States Patent #2,052,777.

The plungers |22 are slidable in a bracket |25 which is attached to the circular base of the machine, and each of these plungers has a spring |26 by means of which it is held outwardly away from the butts on jacks |23 except as moved inwardly by the appropriate discs on drum |20. The drum |20 is rotatable on a movable bar |21, that said bar being capable of swinging about the pivot point |28 and having an elongated arm |29 to which is attached a lever |30. This lever |30 connects through to certain controlling means whereby the drum may be moved outwardly and the plated and reverse plated. control thereby rendered inactive.

The drum |20 is racked periodically by pawls generally indicated by numeral |3| and which are spring pressed by springs |32 to engage a ratchet wheel |33 all as described in the patent just about mentioned. The mechanism for that purpose which is illustrated here includes the movable lever 19 before referred to, a connecting link |34, the pawls |3| and ratchet wheel |33. Retiming mechanism is also provided, but is not shown here since the same is described. in United States Patent #2,052,777 and in other patents. A

Now referring to Figs. 6, 7, 8 and 9, the auxiliary yarn designated by ais fed through a yarn feeding nger |35 which slides vertically in a. small crosshead |36. This finger |35 is moved by a lever |31 pivoted at |38 and connected by means of a depending link |39 to certain cams on the cam drum 22. This link |39 is guided in a bracket |40 and is engaged by cams |4| and |42, Fig. 27. The link |39 is forked at its upper end to `engage about the outer end of the lever |31 and is also forked at the inner end to engage a pin |43.

In Figs. 20, 21 and 22, a yarn binder for the auxiliary yarn is mounted on a bracket |44 and includes binder elements |45 and |46. The element |45 is movablel and .is held upwardly or in closed position by means of a spring |41 except when opened by movement of lever |418 also pivoted at |38. The lever |48 also projects to the other side. of the pivoted end and is engaged by the forked end of a second vertically disposed link |49. That link projects downwardly to be guided by the element |40 and contacts certain cams |50, |5| and |52 on the drum 22.

The binder, when opened, engages the auxiliary yarn a, as shown at Fig. 22, and thenwhen closed, cuts that yarn and binds it in a known manner. The fixed binder element |46 of the binder is pressed by means of a spring |53 against the movable blade |45.

Spring 14| maintains the cutter and binder in closed position and forces the link |49 downwardly against the cams on the drum. A spring |54 connects to the outer end of lever |31 and to a iixed point on the supporting'bracket and likewise, moves that lever |31 and the bar |39 so as to withdraw the auxiliary. yarn from feed ing position and maintain the bar down against its cams onv the drum. All of this mechanism is supported on a bracket |55 which is in turn secured to the top surface of the carrier ring 5.

The cams |4| maintain the auxiliary yarn in feeding position throughout the knitting of the top and of the leg. Then in the foot cam |38 controls and that particular cam has two projections numbered |56 and |51 by means of which the yarn feeding finger is moved downwardly to ay greater extent than for normal feeding so as to get that auxiliary yarn into all needles rather than into every other needle. The purpose of this is to make sure that there will be no eyelet when the yarn goes in and when it comes out, the rst being at the close of the heel and the second at the start of the toe.

The cams which actuate the binder and cutter function as follows: Cam |50 opens the binder and cutter to allow the auxiliary yarn to be introduced to the needles at the start of the top. Cam |5| opens that-binder and cutter so as to take the auxiliary yarn and cut and clamp it after finishing the leg and upon entering the heel of the stocking. Then at the start of the foot cam |52 causes the cutter and binder to open so that the yarn will be introduced to the needles, then holds those elements open so that upon completion of the heel, the yarn will be taken as shown in Fig. 22 and cu-t and clamped.

Referring to Fig. 29, cams, feeding means, pathways of needle hooks, needle butts and jack butts are shown. The needles |58 have butts |59 and at the left of the figure, those butts are moving along in the pathway |60 as they are guided by the raise cam |6|. Jacks are leveled as the master butts 45 are raised above cam 162. Then as those jacks are selected corre- .sponding needles are raised to take the auxiliary yarn, such selecting being accomplished as some one of the butts 42 or 43 engages a selecting plunger 51. After this preliminary selecting movement,.master butts are engaged by cams 58 and the-jacks will be raised so that needle butts reach a pathway |64 and vneedle hooks take yarn a.

Thereafter jacks are immediately moved downwardly by cam 59 while stitch cam 90 draws al1 needles down, the yarn a being knitted by those needles which took it in their hooks. It is floated behind other needles. The level |64 for the needle butts is such that latches are cleared preparatory to taking the new yarn.

After passing the auxiliary feeding and knitting point needle butts are again raised to a point |60 by raise cam |65. At the plungers 40,

'a second selection takes place and master cam |66 will raise selected jacks so that corresponding needles are elevated to a point where butts pass along in pathway |61.

That is a wrap level and the hooks of those needles reach the pathway |68 taking wrap yarn w fed by eyelets such as the eyelet |3 in disc l2. lPreparatory to being selected, a cam |69 levels Jacks and the top instep cam |10 levels needle butts providing some of those butts might be riding above cam |65. 'Ihe .cam |10, extends horizontally at |1| and then terminates in a cam point |12, the latter acting to move wrap needles down so that they will ilrst engage the front stitch cam |13 to be raised slightly before passing under center guard cam |14. The nonselected needles ride along above cam |15 and engage the front stitch cam thereby being raised to clear their latches. The needles selected to be wrapped would have cleared their latches prior to being wrapped. All needles take the main yarn or yarns m fed by one of the main yarn levers 8. After taking that yarn, those needles are drawn down as their butts move down the rear stitch cam |16. The center raise cam |11 performs the usual function. All jacks are lowered by cam |15.

In knitting fabric according to the method and with the machine herein described, two yarns are preferably fed at the main feeding station and one of those yarns is so selected as tomatch in color and appearance the auxiliary yarn a. At the plain areas, so-called, that matching yarn is used to plate over the other yarn fed at that side in those courses knitted at the main side. In this way the plain areas are of a single color and yet, the yarn at the auxiliary' side and that at the main side are primarily of different colors so that in the pattern work there are `two basic colors plus other colors for the Wrap yarn. In these plain areas the control for sinkers as described with respect to Fig. l2 provides for reverse plating of the two yarns at the main side so that the above mentioned result is attained. Of course, other methods oi plating and reverse plating may be employed, but this preferred method and mechanism are described by Way of example.

Now referring to Fig. in which a section of fabric is illustrated, and in which the knitting runs from the bottom to the top of the figure, course |18 is knitted at the auxiliary vside and from the yarn a. In the so-called raised or face areas, that yarn is knitted at alternate wales and floats as at |19 behind intermediate wales. The wales |80, |8|, |82, |83 and |84 are so knitted as to constitute a raised or face area of the fabric. At the next course |85, and at raised areas, the main yarn m is knitted at each Wale and is plated over a second yarn knitted at the main feeding station and which matches yarn a insofar as color or vappearance goes. That plating yarn is designated as yarn a' and is of about the same size as yarn m so -that when reverse plating takes place the yarn m will be covered or hidden;

At the wales |86, |81 and |88, a so-called plain area which appears at a lower level as compared to the face area, is formed Iby knitting yarn a at each alternate course and yarns m and a' at intermediate courses. At these areas the yarn a reverse plates so as to cover the yarn m. Since the yarns m and a are of contrasting colors, the raised areas and plain areas appear of those different colors and the fact that yarn a is knitted in the raised area, and is of a different color from m, does not detract from the clear, single colored appearance oi those areas since yarn a is very iine and is drawn into rather tight stitches. It also floats in back of the wales |80, |82 and |84 and pushes those wales to the front giving aribbed appearance and concealing the wales |8| and |83.

' The general pattern shown in this Fig. 30 is that of a chain stitch or link type of pattern ning upwardly and the raised patterned areas at the right of the plain area running through the center are similar except they are stepped up a few courses so that there is a diagonal connecting line runfrom right to left through the central plain sections.

A wrap yarn wraps in the Wale |90 and then crosses over wrapping in every other wale tothe Wale |9| at the left hand side. This wrap yarn is of a third color and is wrapped so as to4 stand out at the face wales of the raised areas. Of course, this is only illustrative of one particular pattern and there are many other patterns and variations of wrap striping designs possible of being used. It is also true that the shape of the raised and plain areas may be varied in contour or in size, that illustrated here being merely one possible pattern.

Operation In knitting a stocking of the type herein described, at the start of the top, an edge such as an outturned welt or the like is first produced whereupon the top is shifted as a 1 x 1 simulated rib top or of accordion type fabric. At 4that time the toe of lever |02 rides up on cam |06 pulling the top lever 53, Fig. 3, in a direction to push in the topmost plunger 51. That causes every other needle to be brought up at the auxiliary feed to take yarn a and at the main feed all needles knit a yarn.

At the completion of the top the leg is started and to form the raised pattern, cam |06 still continues to control through the top plunger 51 so that every other needle will always be raised at the auxiliary side. However. at that time, the second lever drops from the cam ||3 allowing the drum 5| to move into position so that the pattern set up on that drum may control the remainder of the plungers 53. Then the raised areas will be made at such points as alternate needles take yarn a while at plain areas the pattern means will cause all needles to rise at that side knitting yarn a at each IWale in those plain areas. Of course, at this time the knitting cam is in against the cylinder since neither of cams ||8 or ||9 heretofore, cam |50 also opening the binder at that time so as -to release the yarn for feeding.

After knitting the leg and upon starting the heel the yarn a will be withdrawn as link |39 drops from cam |4| while cam |5| will again open the binder to receive the withdrawn yarn. Then during the heel the pattern drum 5| is moved away from the levers 53.V That is accomplished as the second lever is raised on cam H4. Ratcheting of drum 5| is then discontinued throughout heel knitting. At the same time the third lever |5 is raised by cam ||9 and the stitch cam 90 moves away from the cylinder to an inactive position. The lever |02 is also dropped from cam |06 and the top plunger 51 is withdrawn so that Jacks are not affected.

At the close of the heel and start of the foot, lever |02 is again raised by cam |01 and the foot is knitted with a pattern in the instep but merely as a 1 x 1 mock rib in the sole. The pattern drum 5| again moves to active position and cam 90 moves into its butt engaging position.

There is a. plain sole cam (not shown but similar to that shown at 46, Fig. 14) at the auxiliary side and that works upon `butts 43 to prevent a pattern .being knitted similar to that in
